Across:| 1. | Excessive loss of water from the body or from an organ or body part, as from illness or fluid deprivation. | | 6. | A contractile organ consisting of a special bundle of muscle tissue, which moves a particular bone, part, or substance of the body. | | 10. | A type of animal tissue made up of densely packed cells that rest on a basement membrane to act as a covering or lining of various bodily surfaces. | | 12. | A group of cells working together to perform a specific function. | | 16. | The sensitive connective tissue layer of the skin located below the epidermis, containing nerve endings, sweat and sebaceous glands, and blood and lymph vessels | | 17. | Any of a group of naturally occurring dark pigments, especially the pigment found in skin, hair, fur, and feathers. | | 21. | The proximal end of the nail, concealed under a fold of skin. | | 22. | Tissue arising chiefly from the embryonic mesoderm that is characterized by a highly vascular matrix and includes collagenous, elastic, and reticular fibers, adipose tissue, cartilage, and bone.
